AB  - Zwitterion-functionalized polymer microspheres (ZPMs) have been designed and used 
      as the core adsorbent for the selective and rapid enrichment of mercury species 
      in environmental waters by an on-line solid-phase extraction (SPE). Zwitterionic 
      S-ZPMs and N-ZPMs having an anionic sulfonic group, but differing in cationic 
      S(+) and N(+) moieties were prepared from Merrifield resin by treating with 
      1,2-ethanedithiol and imidazole, followed by modification with 
      1,3-propanesultone. Without any additional reagents, inorganic mercury (In-Hg), 
      methylmercury (MeHg) and ethylmercury (EtHg) were quantitatively adsorbed on the 
      home-made mini-column packed with ZPMs. Following extraction with 60 mM ammonium 
      acetate and 0.15% L-cysteine (L-Cys) solution within seconds, separation and 
      speciation of mercury were successfully achieved by the HPLC-ICP-MS technique. 
      Under the optimized experimental conditions, the enrichment factors (EFs) are up 
      to 105 and 98 for inorganic and organic mercury only with 40 mL sample solution, 
      respectively. The low detection limits of 0.78 ng L(-1), 0.63 ng L(-1), and 
      0.49 ng L(-1) were reached for In-Hg, MeHg and EtHg, respectively, with the 
      relative standard deviations (RSDs) below 4.1%. The feasibility and accuracy of 
      the on-line SPE-HPLC-ICP-MS method were successfully applied for mercury 
      speciation in surface water, seawater as well as certified reference material 
      (CRM). The results here demonstrate a facile, sensitive and selective method for 
      speciation of mercury at trace levels.
